This is a HOWTO for Yum: the Yellowdog Updater, Modified. Yum is
an automatic updater and package installer/remover for rpm-based
systems. It automatically computes dependencies and figures out what
things should occur in order to safely install, remove, and update rpm
packages. Yum also efficiently and easily retrieves information on any
package installed or available in a repository to the installer. Yum
makes it easier to maintain groups of machines without having to
manually update each one using rpm or other tools. Yum can manage
package groups, multiple repositories, fallback repositories and more
to permit centralized package management performed by just one or two
individuals to scale over an entire organization.
Note Well! This HOWTO is in a state of total flux during
its initial pre-release development. Lots of sections are empty, others
are wrong, all is in a state of mediocre organization. Nevertheless, I
cherish feedback from anybody on the basis of any snapshot you happen to
see.
